Hebe `Margret`

ABSTRACT

A new and distinct cultivar of Hebe having a semi-dwarf to dwarf compact habit. The selection is a profuse bloomer in late May to early June with later flushes in late summer and fall, especially if earlier dead flower spikes have been removed. The flowering racemes stand well above the foliage. Individual blossoms are initially of sky blue color. These fade to a paler blue and then to white, giving an unusual bicolor effect. Because of its compact habit the plant is ideal for use in borders or in containers.

The present invention relates to a new and distinct dwarf or semi-dwarf variety of evergreen shrub of the genus Hebe, a member of the Scrofulariaceae or Figwort family.

This new Hebe is the result of a breeding program and is a cross between Hebe `Carl Teschner` and Hebe `Mauve Queen`. The new variety has been reproduced from cuttings. Each of the progeny of the first and succeeding generations exhibit characteristics identical to those of the mother plant. The parents were chosen in an attempt to reproduce the hardiness of Hebe `Carl Teschner` with the profuse flowering ability of Hebe `Mauve Queen`. This particular selection appears to have accomplished that goal. It has the added characteristic of flowering for a longer period than is usual in the Hebes tending to dwarf habit. These dwarf-tending Hebes most often have small flower spikes in relation to the size of the shrub so that the flowering plant appears to lack continuity. Hebe `Margret` is a profuse bloomer with relatively large flower spikes. It presents the appearance of an entire shrub being in synchronous heavy bloom rather than showing irregularly distributed blossom spikes.

The habit of Hebe `Margret` is distinct in that it has the upright characteristics of a taller growing variety with the many flower spikes appearing well above the foliage. This is in contrast to other dwarf Hebes that in many cases have a sprawling habit. The sky blue flower spikes appear in profusion in late May followed by several flushes in late summer and fall, sometimes as late as December. Other Hebes of similar size tend to have an initial flowering period with only spasmodic flowering to follow. As time passes the flowers fade to pale blue and then to white producing an unusual bicolor effect. Continuity of flowering is encouraged by removal of dead flower spikes.
